🔧 Update Go module dependencies and modify NATS configuration to exclusively support JetStream mode. Upgrade go.uber.org/zap to version 1.27.1 and golang.org/x/crypto to version 0.45.0. Revise Makefile and documentation to reflect changes in NATS mode, ensuring consistent messaging behavior across development and production environments. Enhance README and configuration files to clarify JetStream usage and remove references to Core NATS mode.
